- they show extinct animals and the characteristics that change or have changes over time. 
- show that evolution exists and how organisms have evolved over time. 
- show how organisms have change over time. 
- show progression of organisms over time. ]]> 2018-10-11 01:12:06 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/291523072 What is evolution? bryers https://padlet.com/bryers/cl4z5fh05blo/wish/291524407 - process of an organism adapting to become stronger and a better version of itself. 
- species evolving and changing overtime. 
- adaption

- food chain positions.
- breeding amount + progress. 
- hunting and eating. 
- natural disasters/global warming. 
- natural selection. 
- human impacts. 
- some species have evolved much faster which keeps them from becoming extinct. 
- type of environment 
- food availability. ]]> 2018-10-11 01:20:24 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/291524839 Has evolution stopped bryers https://padlet.com/bryers/cl4z5fh05blo/wish/291525581 - no :) animals are alway becoming stronger and better suited. 
- when species become extinct.
-  no, because our environment is always changing and we develop to adapt to the environment. ]]> 2018-10-11 01:24:03 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/291525581 Why do Australian animals differ from African animals? bryers https://padlet.com/bryers/cl4z5fh05blo/wish/291526066 - they ave different surroundings.
- environmental pressures caused adaption.
- different appetites
- different environments 
- different predators and prey availability
- they come from different habitats and climates.

Extinction: the fact or condition of being extinguished or extinct.
Fossils: any remains, impression, or trace of a living thing of a former geologic age, as a skeleton, footprint, etc.
Species: a class of individuals having some common characteristics or qualities; distinct sorter kind.
Asexual Reproduction: reproduction, as budding, fission, or spore formation, not involving the union of gametes.
Sexual Reproduction: reproduction involving the union of gametes.

Australian ecosystems have high biodiversity.
Overall, Australia is home to almost 10% of the world’s biodiversity. It is also home to a high number of endemic species. These are only found in Australia, because it has been isolated from other continents for millions of years. Australia is one of the mega diverse countries in the world. ]]> 2018-10-17 06:49:29 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/293702379 Compare and contrast absolute and relative dating of fossils. bryers https://padlet.com/bryers/cl4z5fh05blo/wish/293704043 difference: absolute dating gives us a more specific age of fossils, relative is only a comparison, did it come before or after another fossil]]> 2018-10-17 06:55:17 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/293704043 should we use genetic technology to bring back to extinct species?

Relative Dating: is the science of determining the relative order of past events, without necessarily determining their absolute age.
Homology: the state of having the same or similar relation, relative position, or structure.
Homologous Structures: of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
Divergent Evolution: is the process of tracing back two or more species to their common ancestor.
Vestigial Organs: Vestigial organs are organs of the body which are smaller and simpler than those in related species.
Bioinformatics: the science of collecting and analysing complex biological data such as genetic codes.]]> 2018-10-17 06:59:06 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/293705090 ... bryers https://padlet.com/bryers/cl4z5fh05blo/wish/293708210 2018-10-17 07:10:30 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/293708210 Week 3 bryers https://padlet.com/bryers/cl4z5fh05blo/wish/296296888 2018-10-24 06:26:31 UTC https://padlet.com/bryers/cl4z5fh05blo/wish/296296888
